Title: Comb filter separating video spectra in PCM TV system - uses digital delay cct. and adder and subtractor
IPC: H04N7/24
Filed: 1969-08-08
Abstract: The comb filter, for separating video spectra in PCM television transmission systems, has the FBAS input signal passed to a delay circuit in digital form as a parallel or serial code. The delay circuit consists of a shift register, monostable flip-flop or similar. The output of the delay circuit is added and subtracted from the original input signal to obtain the luminance and the chrominance signals. The signal may be applied to the delay circuit before A/D conversion in which case the delay circuit is constructed from analog components. The filter avoids the problems inherent in delay circuit's that use analog techniques.

Title: Heating unit for railway points - has ignition electrodes and torch head connected to gas line movable along rail
IPC: F23N5/20
Filed: 1970-11-11
Abstract: The ignition line (11) incorporates a pair of ignition electrodes (301, 302) which are connected to a high voltage produced by a coil (303). This coil is placed as close as possible to the electrodes so that the connecting line is short. The electrodes, supply heads and the coil are located in an air- and water-tight housing (14a). Fuel gas flows along its supply line (9) to the ignition line (11) via a branch connection (16b) and is then ignited in the ignition line by the coil and the electrodes. As soon as the gas is alight, the flame is conducted through the complete line and branch line to the torch heads. This obviates the necessity of using electrodes made of heat-resistant material.

Title: Passive optical surveillance device - has azimuth and elevation scanning, with multi-detector at image plane
IPC: G01S3/789
Filed: 1972-04-15
Abstract: The main objective lens of the surveillance device collects the incident ray onto a canted mirror which rotates about a vertical axis with a speed of revolution half that of the azimuth scanning speed. By the corresponding choice of the direction of rotation, an image rotation is produced, which exactly compensates the tumbling of the image. The reflected beam is again diverted by a mirror in such a way that the new beam of light rays, coincides with the vertical axis of rotation, and then goes through a polygonal prism which produces the elevation scanning. A multi-element detector is situated behind the image plane. (DS).

Patent JP-H0432373-B2 (JP)
IPC: G03B27/42
Filed: 1982-02-19
Abstract: Sheets are fed to a reciprocating carriage 27 along a guide 28. The leading edge of a fed sheet engages the nip between a freely rotatable roller 32 and the carriage surface. As the carriage moves forward (to the right in this figure) the sheet is engaged by the nip and feeds on to the carriage surface. Thereafter, as the carriage returns, the sheet is engaged by a nip between the surface and roller 34. This roller is either prevented from rotating or is caused to rotate against the surface motion during carriage return, so the sheet is ejected into tray 36.

IPC: G10L19/00
Filed: 1980-03-12
Abstract: The synthesizer comprises a lattice filter (TV) which simulates the vocal tract and generates speech samples by processing samples of excitation waveforms on the basis of suitable coefficients. The excitation waveforms, which are either periodical, in case of synethesis of a voiced sound or pseudorandom, in case of unvoiced sound, are supplied by respective generators (EP, EC) connectable to the filter (TV) upon command of a signal indicating the voiced-unvoiced nature of the sound. The filter coefficients and the information on the nature of the sound, together with the pitch period in case of voiced sounds and the sound intensity, are supplied to filter TV and to the excitation generators (EC, EP) by an external unit (UE), where they are stored, through a plurality of input modules (INa... INn) and a control unit (UC) acting as an interface towards the external unit (UE). The input modules (INa... INn) effect a temporary storage of the synthesis parameters supplied by the external unit, and updates the filter coefficients at the beginning of each pitch period, in case of voiced sound, or at the beginning of a validity interval in case of unvoiced sound. 
<??>The input modules are associated each to a synthesizer channel, and the excitation generators (EC, EP) and the filter (TV) are time division multiplexed over the various channels of the synthesizer.
